MEG rejectvisual summary

[Akiko Ikkai]

Hi,

I'm working on MEG data, and I have a very basic question on rejectvisual, with cfg.method  = 'summary';

I understand that on channel number and trial number graphs, x- and y- axis (respectively) are variance across trials and channels. My question is what the acceptable range of these values are. SQUID jumps would be very obvious, but how about slow drifts (due to movement)?

I suspect this depends on data, but if anyone could suggest some starting point (maybe based on experience?), I'd very appreciate it.

Thanks! Akiko
